First I picked off the Franklin county highpoint, then it was on to Tekoa Mtn (Whitman County), then Ray Ridge's HP for Asotin county, and finally Diamond Peak and the two other spots. After that, I drove down to the Eagle Cap TH and spent the night before doing Eagle Cap the next morning.
It was a blur of a day.

I summited Diamond Peak (and the other Garfield County candidates) in the middle of a long day in which I first summited Oregon Butte and last summited the Asotin County highpoint candidates. Garfield County was my 15th WA COHP.
